Live Webinar - Driveline Modeling and Simulation: Challenges and Solutions for HIL SimulationWednesday, March 21st, 2012 at 10:00am ET

In this webcast, Dr. Derek Wright, MapleSim Product Manager, and Dr. Orang Vahid, Senior Modeling Engineer, at Maplesoft will present some of the challenges faced by hardware- and software-in-the-loop (HIL and SIL) simulation of complex driveline models. These models present unique difficulties to engineers wishing to do control design and validation via HIL and SIL simulation. Specifically, there is often a trade-off necessary between model fidelity and simulation speed that may necessitate model approximations and result in reduced effectiveness of the designed controllers. Discussion will include the role of Modelica and acausal modeling in achieving manageable physical models and how symbolic formulations can increase simulation speed without reducing model fidelity.

Recorded SAE Webinar: Physical Models of Automotive Batteries for EV and HEV Applications

The automotive industry is in transformation. New generation vehicles deploying hybrid (HEV), fully electric (EV), and fuel cell powerplants are presenting significant challenges to automotive engineers. The complexity of the automobile has increased exponentially in the past decades with higher performance components and digital control. This has triggered a design revolution in the industry which stresses detailed modeling and simulation steps prior to committing to metal and plastic. With new generation vehicles the need for advanced physical modeling solutions is considerably greater due to increasing system complexity, and the battery is becoming one of the most critical components in alternative powerplant development.

This webinar covers new approaches to modeling and simulation for hybrid electric vehicle (HEV) and fully electric vehicle (EV) applications with particular emphasis on the development of high fidelity physical models of automotive batteries. Developed as part of the research program for the NSERC/Toyota/Maplesoft Industrial Research Chair for Mathematics-based Modeling and Design, these models will plug into comprehensive system models for HEV and EV applications. Conventional lead-acid, but also NiMH and Lithium battery models will be presented.

From simple and intuitive model entry to insightful and complex analysis, this brief demonstration will illustrate how these tools allow you to assess the stability, controllability and sensitivity of your engineering system designs.

Dr. Lai is using MapleSim and Maple to help the team understand the principles involved and design their basketball-shooting robot. There are a number of factors governing the trajectory of a projectile. For the purpose of the competition, each team is really looking at what combinations of the shooter launch speed and launch angle for a given location within the game arena would be best to maximize the scoring.
